    摘要: A FAWNA that allows high-speed mobile connectivity by leveraging the speed of optical networks. Specifically, SIMO FAWNA, which comprises a SIMO wireless channel interfaced with a fiber channel through wireless-to-optical interfaces. Received wireless signal at each interface are sampled and quantized prior to transmission. The capacity of the FAWNA approaches the capacity of the architecture exponentially with fiber capacity. It is also shown that for a given fiber capacity, there is an optimal method of operating wireless bandwidth and number of interfaces. An optimal method to divide the fiber capacity among the interfaces is shown, which ensures that each interface is allocated a rate so that noise is dominated by front end noise rather than by quantization distortion. A method is also presented in which, rather than dynamically changing rate allocation based on channel state, a less complex, fixed rate allocation may be adopted with very small loss in performance.

    摘要: Certain aspects of the present disclosure provide a technique for bundling the received service data units (SDU) in a first communication layer to generate a protocol data unit (PDU) to pass to a second communication layer. For example, one or more packet data convergence protocol (PDCP) SDUs may be concatenated to generate a PDCP PDU and be sent to a radio link control (RLC) layer in the transmitter side. Similarly, one or more PDCP SDUs may be extracted from a PDCP PDU in the receiver side.

    摘要: Systems and methodologies are described that facilitate dividing scheduling algorithms into background and foreground aspects capable of simultaneously servicing a multiplicity of disparate flows in wideband communications networks. The systems provided herein arbitrarily select prospective time horizons, generate optimal bandwidth allocation targets based on a plurality of flows observed by the system, and utilizes the optimal bandwidth targets to assign flows to users over the entirety of the prospective time horizon.

    摘要: A network device connected to a base station via a backhaul connection may be operable to determine whether the backhaul connection is congested. The determination may be based on a periodic data cap imposed on the backhaul connections. In response to a determination that the backhaul connection is congested, the network device may configure one or more cellular communication parameters of one or more of the plurality of base stations. The determination may be based on one or more of: a total amount of data consumed over the backhaul connection during a current time period, a traffic load on the backhaul connection, and an amount of time remaining in the current time period.

    摘要: A network device may make a determination that a first backhaul connection, which serves a first base station, is congested and that a second backhaul connection, which serves a second base station, is not congested. This determination may be made based on a first periodic data cap imposed (on the first backhaul connection, a traffic load on the first backhaul connection, a second periodic data cap imposed on the second backhaul connection, and a traffic load on the second backhaul connection. In response to the determination, the network device may configure a value of a cellular communication parameter utilized by one or both of the base stations. The configuration may comprise periodic adjustments of the value of the cellular communication parameter. The periodic adjustments may cause one or more mobile devices to be cyclically handed-over between the first base station and the second base station.

    摘要: Systems and methodologies are described that facilitate dynamically adjusting scheduling priorities in relation to a combination of delay sensitive flows with delay requirements and best effort flows. The systems and methodologies provide optimal and efficient techniques to enable real time adjustment and assignment of bandwidth for a combination of best effort flows and delay sensitive flows. In particular, the bandwidth allocation is adjusted for each data packet such that delay requirements are met and the remaining bandwidth can be assigned to best effort flows.
